This thread isn't for justifying my motives for doing it, but if you must know:- 1) I enjoy working on the car and trying new parts. It's just a hobby. 2) Because I had to change the pump anyway, and thought I may aswell try the newer stuff whilst I was down there as it's barely any more money than the old 12V stuff. 3) Because you said it yourself, with all the time and money invested in my engine, it makes sense to protect the crank from running dry, despite the fact I'm unlikely to ever track it. Yes I initally questioned the need for it, but I'm entitled to change my mind and the parts
